"Deprecated" != "deprecated in favor of RTP"
And then we need to add all the RTP variants, and the UI becomes huge.
I definitely prefer the drop-down list.

Sure, but... Raw UDP is only used to talk to legacy boxes. I am yet to find 
the protocol that makes HTTP "legacy".

TS is not free from early synchronization issues either.

That's a start.

But your opinion is totally biased.

For plain MPEG-2 audio audio streaming, plain RTP is actually better.
There are also cases where TS simply will not work, e.g. streaming to 
PulseAudio.

There are no past releases of the Qt4 interface. And then, the whole stream 
output panel is so usability-challenged, that I really don't see TS disabled 
by default as any significant issue.
